APPARATUS F. BUSHING COAL T'UBS.

Application filed September 16, 1924.- Serial No. 788,107.

To all whom it may concern:

Be it known that I, ALBERT EDWARD Bosn,

a British subject, residing at Stone Lea,

Parkgate, Rotherham, Yorkshire, England, have invented certain new and useful Improvements in Apparatus for Pushing Coal Tubs, of which the following is a specification.

This invention relates to improvements in or connected with apparatus for unloading full and loading empty wagons or corves into the mine cages and ofthat kind in which pivoted pushing arms or the like are adapted to engage one or more wagons in line or side by side on separate rails, and to push same into the cage, the said arms then returning to the initial or ready for use position and turning on their pivots into lowered positions to which the said arms or equivalents are rocked or turned by their engagement with a fixed stop or stops adjacent to the rails, or according to one construction of my invention by tipping a bogie on which the arms are mounted.

These buffer arms can be actuated by hydraulic or other means, or I may employ compressed air, steam or anelectric motor.

I will describe the invention more particularly as constructed for operation hydraulically and in which the fiuid is charged into a cylinder fitted 7 ton. The/cylinder is permanently fixed in a horizontal position preferably on the centre line of the machine, the piston rod end being secured to a bogie or travelling car which moves to and fro in a horizontal line, having suitable wheels which run in steel channels say between the two parallel sides-of a steel girder of H section andwhich may advantageously form the framework of the machine.

- The machine can be used for cages where two or three'wagons are charged into the cage-side b side provided the framework is sufficiently wide tocarrythe bogie or travelling car necessary for each set'of wagons.

The length of the framework is determined by the number and len th of wagons to be charged into the cage by one thrust of the machine. r

Vertical arms are mounted on the bogie and are designed to suit the buffers of the with'a piston rod and pis-' wagons, and there will be provided one arm w th bufi'ers attached to the to for each set of wagons to be charged si e by side. The arms may be rigid with or pivotally attached to the bo ie and when pivoted the lungs of the arm 1s fitted to the bottom of. the bogie and in such manner that the and rests against the top side of the bogie, thus preventing it from moving from the vertical position when the machine is in operation.

If rigid arms are used the track on which the bogie travels is turned downwardly at the rear or cylinder end of the travel and so tilts the bogie and turns the arm downwardly. The hin ed bufier arm is held in -a vertical position y a strong spiral spring preferably fitted into a tube connected to the framework of the machine, and in such manner that the, arm can by contact with a stop on the framework be lowered sufiiciently at the end of the return stroke for it to be out of contact with the wagons which are being put into position.

The moygeg ent of th e bogie is obtained by moving a lever whi'c'liis connected to a suitable valve. When the lever is moved in a forward. direction the valve admits fluid to :the rear end of the cylinder. The pressure forces the piston, piston rod and bogie forward. The arm leaving the stop as the bogie moves forward is pulled by the spring into the vertical position (or is turned upwardly by the bogie reassuminm its horizontal position), when the buffers o the arm will come in contact with the buffers on the empty wagons and push them into the waiting cage, at the same time discharging the full wagons from the cage. The valve lever is then reversed, which admits the pressure to the front end of the cylinder, which pushes back the piston, piston rod, and bogie to the rea'r'o'f the frame. To prevent the forward movement of the bogie when the cage is not in the osition for being charged, a safety lever is p aced in a suitable position and operates a catch, which secures the bogie, thus preventing it moving until required. a

As an additional safeguard the operating lever is held whilst the gate is down as by a projection or equivalent on the gate engag i in" the lever or an arm thereon. will now describe my invention w th reference to the accompanying drawings in which:

Figs. 1 and 1 together show a partial side view of the apparatus and show also by line and dot a cage and wagons.

Figs. 2 and 2 together show a of the apparatus seen in Fig. 1.

Fig. 3 is a broken elevation, partly 1n section, showing the butter arm atthe operative limit of movement.

Fig. 4 is a similar view showing the buffer arm depressed to permit the wagons to pass thereover. Fig. 5 is a broken front elevation showing the mounting of the bogie truck.

Fig. 6 shows an alternative means for tippirl pg the bufier arm, and

ig. 7 is, a diagrammatic view showing a general lay-out of the apparatus.

plan view Referring to Figs. 1 to 5 and Fig.7, the

" ca e a and wagons b are of the usual kind, ar i the latter are adapted to run on rails 7 0 into and out of the cage. M apparatus comprises the cylinder 1 in which is a piston 52 with rod 3 connected to a bogie 4 adapted to travel to and fro on steel joists 5, see Fig. 5.

Attached to the front of the bogie is a pivoted buffer arm 6 to which a spring-controlled rod 7 is connected and adapted to hold the arm in vertical position. This spring is enclosed in a tube 8. A valve 9 is fixed to the cylinder 1 and is controlled by a lever 10 to which it is connected by an ad'ustable rod 11. Fluid pressure is admitted to the cylinder b pipe 12 and according to the position 0 the valve will thrust the piston one way or the other and thus move the bogie to or from the cage.

A cross bar or stop 13 is'arranged to contact with the buffer arm when it approaches the end of its rearward travel and is adapted to push the arm downwardly against the spring action, andthus allow wagons to be ushed over the arm which rises on the Initial outstroke of the piston rod and reassumes its upright position so as to contact with the rearmost wagon and push it into the cage. p

A gravity catch 14; is provided to engage the bogie when it reaches the end of its rearward travel. This catch is lifted by an arm 15 connected to the valve and so arranged that it is operative only when the 'lever 10 is moved toactuate the valve for the purposeof pushing the bogie forward.

The three positions of the lever are seen 1n Fig. 1. The foot of the lever has a shouldered plate adapted to engage a projection 16 movable by the gate of the cage when it '18 fully raised. The construction is such that with the gate down the lever cannot be moved to operate the plston for the forward movement of the bogie and thus collision be-/ 4. An tween the wagons and. the gate is averted. ons into The bogie may be adapted to strike the lover or a part connected to it when the bogic is close to the cage gate so as to reverse the lever and bring about the automatic return of the bogie or stop its forward movement.

In Fig. 6 an alternative means of turning over the buffer arm is illustrated diagrammatically. In this case the bbgie shown at 20 has wheels or rollers 21 travelling on the steel joists 22 which are curved downwardly at the rear end of the bogie travel so as to tip the bogie and turn the bufi'er arm downwardly. This construction dispenses wlth the use of springs. The piston rod is shown at 23. If electric power is employedjn place of the hydraulic, steam or air, several methods of carrying out my invention may be adopted. As an example the bogie may be made to contact with a lever at about each end of its travel and these levers may control a reversible electric motor adapted to draw the bogie to and fro with safety means for preventing the forward movement until the wagons have been pushed into position. As another example, the bogie may carry a reversing gear which is actuated bycontact with fixed stops so that its direction of travel isreversed at eachend, or the bogie may carry a motor which drives a toothed wheel engaging a rack between the rails,

said motor, or its drive, both endsof travel.

What I claim is: 1. An apparatus for pushing empty wagons into mine cages, comprising a bogie truck adapted to travel to and from the cage, a buffer arm carried thereby, means to lower the arm in one position of the truck for permitting the wagons to travel over the arm, and means for holding the bogie being reversed at truck against movement when the arm is lowered.
